Which Replication Type Is Best
May 29, 2001
Hi All,
I have a situation in my project. It's like this:
One Server running SQL Server2000 is located in NewYork (Primary Server). Another server running SQL Server2000 is located in Chicago (Secondary Server). Both the servers physical location is NewYork and Cicago respectively.The front end application is a web application (ASP,HTML/DHTML,VB/Javascript,IIS).
The requiremnet is they want to replicate the data in NewYork server to Chicago server. So that if NewYork Server fails, Chicago server will take over. The user will not know this. To the user it appears the server is always available.
Once the NewYork server is up, Uptodate data from Chicago server should be updated to NewYork server.
Hope people understand my requirement. Which type of replication is best for this scenario - transactional, Snapshot or Merge?
Appriciate any help. Thanks in Advance.

WE have two offices A and B linked with least line. WE have a set of client-server programs which will be used for both offices. one of the SQL server 2005 located in A. I have done some test to run the programs in office B using ODBC, ADO, etc and found out that the performance is so unacceptable. Therefore, now I decide to set up a replication server in office B. However, I don't know what type of replication should I use.. Merge or Transactional with update??
Please help..THX in advance

We are replicating data from server1 to server2. We expect the connection between servers to be reliable, but we can not always guarantee uptime on both ends. We do not need real-time data access on server2. What type of replication would be best? The downside we see to snapshot is that the data will be growing over time and that means the amount replicated will continue to grow. Can we setup transaction replication and then schedule the updates so it only replicates transactions since the last update? Does this present any problems if the connection is lost at any time between the servers? At this time, we will not be making any changes to the data on server2 so it does not need to be updated on server1.

Hi All,
I am new to MSSQL Server 2000. I am sorry if you think that this is silly question.
What is the difference between identity – yes and yes(not for replication)
What are two different situations where I should use identity – yes or identity - yes(not for replication)
Thanks in advance

Hi All,
We have installed Two SQL 2000 servers.
DB1 (main database) configured as a distributor and
publishers and DB2 configured as a subscriber (backup
database). The procedures I did the replication:
1. full backup the whole database said "test" on DB1
server.
2. Create a new database "test" on DB2 server
3. restore the full backed up database to "test" database
on DB2
4. create transactional publishes (select all tables) on
DB1 and "push" the articles to DB2
The results of replication monitor for replication all
database's table:
1. sanpshot suceeded A snapshot of 100 articles was generated.
2. LogReader Idle No replication are available.
3. DB2:TEST Failed Invalid column name "TYPE"
If I only select saying 5 articles (tables) to replication
at the same database "TEST". That the result was
successful without any error.
Strange... the "TEST" database was restoring from the full
backup (latest data) of DB1. Suppose that all the tables'
column should be same. How come the error is "Invalid
column name TYPE" and number is "207"
By the way, some of "unpublished objects" including tables
couldn't be select for publishing which is default locked
by a "key with red cross". How can I release such tables
(articles) allow selecting for publishing
Any idea and help?!

what type of replication is best and easiest to startup on the DR site in event of a failover for an SQL server with very high transaction occurring on the database.I normally handle Oracle database and we use SAN to SAN replication to the DR site, all w have to do is mount the replicated disks at the DR site and Startup the database.How do i achieve this on SQL database including having the using logging details work at the DR site.

SELECT
P.Publication
,P.Publication_type
,S.Subscriber_ID
,S.Update_Mode
FROM MSPublications P
INNER JOIN MSSubscriptions S
ON P.Publication_ID = S.Publication_ID
give me publication_type=0. So it is transactional replication but how do we know that is pull or push?

Sql Server 2000
I am looking for bidirectional transactional replication using updatable subscribers (queued or immediate) . Is it possible to replicate the image data from the updatable subscribers to the publisher. I understood that the Image data can't be replicated to the publisher from the updatable subscriber. I am not using the WRITETEXT or UPDATETEXT. I am using just INSERT and UPDATE for image data type transactions.
Any thoughts on this is greatly appreciated.
Thanks in advance

Hi,
I am trying to setup Trans Replication with updating subscriber on sql2000. One column on few tables got data with single quote (').
How do I handle in this case? Did any one come across such case?
Can I Change default QUOTED IDENTIFIER from ' (single quote) to something else (@@@) on SQL2000?
If yes, how to do?
Thanks

Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?

I like to define my procedure parameter type to match a referenced table colum type,
similar to PL/SQL "table.column%type" notation.
That way, when the table column is changes, I would not have to change my stored proc.
Any suggestion?

Hi,
The table in SQL has column Availability Decimal (8,8)
Code in c# using sqlbulkcopy trying to insert values like 0.0000, 0.9999, 29.999 into the field Availability
we tried the datatype float , but it is converting values to scientific expressions€¦(eg: 8E-05) and the values displayed in reports are scientifc expressions which is not expected
we need to store values as is
Error:
base {System.SystemException} = {"The given value of type SqlDecimal from the data source cannot be converted to type decimal of the specified target column."}

Implement time interval type in the form of a user defined type in SS2k8r2? Specifically an interval type described in the book Temporal Data and the Relational Model by C. J. Date at all. As an example, an interval is below:
1/4/2006:1/10/2006
which would mean the time period from 1/4 to 1/10.

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

I have extensively revied both of the design methodologies and I cannot come up with a single clear reason to use one over the other!
Type - Attributes is where you have a table holding the type categories, type, a table holding the type attributes expected and then a table holding the type attribute value:
tbAutombbileCategories
CategoryID | Category
-------------------------------
1 | Car
2 | Truck
3 | Motorcycle
tbAutomobileAttributes
AttributeID | fkCategoryID | Attribute
-------------------------------------------
1 | 1 (car) | Doors
2 | 2 (truck) | Cab
3 | 2 (truck) | Capacity
tbAutomobile
VIN | Category | Make | Model
-------------------------------------
1 | 1 | Honda | Accord
2 | 2 | Ford | F150
tbAutomobileAttributeValues
fkVIN | fkAttributeID | Value
---------------------------------
1 | 1 | 2
2 | 1 | 0
2 | 2 | 1000
Now the above sure is flexible in the sence that a type of automobile can be added without affecting the database schema, but was if some attributes do not take a numeric value? How do you handle computations on attributes specific attributes? Why would I use this structure as opposed to the super type - sub type as shown below?
tbCategories
CategoryID | Category
--------------------------
1 | Cars
2 | Trucks
tbAutomobile (Super Type)
VIN | fkCategoryID | Make | Model
-------------------------------------
1 | 1 |Honda | Accord
tbCars
fkVIN | Doors |
-----------------
1 | 2
tbTrucks
fkVIN | Cab | Capacity
---------------------------
2 | 0 | 1000
Now, adding new sub types probably isn't very flexible but, now you can specify data types for each attribute instead of using sql_variant, which by the documentation cannot be used in aggregate functions and may render poor result when used with ADO.
Regardless of the method used, alot of back end coding is required for computations, what table to send the attributes, etc...
Can anyone please help me clarify. What method is best and why. So far I am leaning for option 2. More work but seems to be more flexible in the sence of customization of each datatype.
E.G., what if you wanted to specify attributes about the cap that can be supplied to trucks?
tbTrucks
fkVIN | Cab | Capacity | fkCapID
--------------------------------------
2 | Y | 1000 | 1
tbCaps
CapID | Vendor | Price | et....
Any thoughts at all? I thought this would have been a pretty damn hot topic!

I'm trying to use the SSIS Execute SQL Task to pull XML from a SQL 2005 database table. The SQL is of the following form:
SELECT
(
SELECT
MT.MessageId 'MessageId',
MT.MessageType 'MessageType',
FROM MessageTable MT
ORDER BY MT.messageid desc
FOR XML PATH('MessageStatus'), TYPE
)
FOR XML PATH('Report'), TYPE
For some reason I can only get this query to work if I use an ADO.NET connection type. If I try to use something like the OLEDB connection I get the following error:
<ROOT><?MSSQLError HResult="0x80004005" Source="Microsoft XML Extensions to SQL Server" Description="No description provided"?></ROOT>
Can anyone tell me why the SELECT ... FOR XML PATH... seems only to work with ADO.NET connections?
Thanks

Dear all,
I am stuck with a SSIS package and I can€™t work out. Let me know what steps are the correct in order to solve this.
At first I have just a Flat File Source and then Script Component, nothing else.
Error:

I get the following message in the vs2005 querybuilder when i do a preview:
***********************************
SQL Execution Error.
Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)
Error Source: SQL Server Compact Edition ADO.NET Data Provider
Error Message: @PARAM1 : Unable to cast object of type 'System.Data.SqlTypes.SqlInt32 to type System.IConvertable'.
****************************************
The same querypreview works fine without the parameter:
SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)
Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error. Dropping the index solves theproblem.Can anyone tell me why an index would cause a query to fail?Thanks a lot in advance,AmirCREATE TABLE [PTRANS] ([CHL#] [varchar] (100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[CHCENT] [numeric](2, 0) NOT NULL ,[CHYYMM] [numeric](4, 0) NOT NULL ,[CHDAY] [numeric](2, 0) NOT NULL ,[CHTC] [char] (2) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]GOCREATE VIEW dbo.vwTransactionsASSELECT CONVERT(datetime, dbo.udf_AddDashes(REPLICATE('0', 2 -LEN(CHCENT)) + CONVERT(varchar, CHCENT) + REPLICATE('0', 4 -LEN(CHYYMM))+ CONVERT(varchar, CHYYMM) + REPLICATE('0', 2 -LEN(CHDAY)) + CONVERT(varchar, CHDAY)), 20) AS TransactionDate,CHL# AS AssetNumber,CHTC AS TransactionCodeFROM dbo.PTRANSWHERE (CHCENT <> 0) AND (CHTC <> 'RA')*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I have a ntext column which stores rows of xml data. Ive decided that the best way to query the xml data is to Convert the ntext data into xml data type and use Sql Server 2005 builtin Xml Query tools to perform FLWOR expressions. The problem Im having is getting the ntext data Converted to xml.When I try to convert the ntext text, I of course get an error that local variables of ntext type are invalid.Any suggestions on a way I might accomplish this?Thanks, -lance

Hi
Is it possibly in SqlDataSource's SelectCommad to convert a text-type value to a date-type value (11/1/2008 (text) -> 11/1/2008 (date) ) , so that order by can be used. Or is the other ways to use order by correctly with text-type (date)values
Thanks.

I'm getting this error on a vb.net page the needs to execute two separate stored procedures. The first one, is the main insert, and returns the identity value for the ClientID. The second stored procedure inserts data, but needs to insert the ClientID returned in the first stored procedure. What am I doing wrong with including the identity value "ClientID" in the second stored procedure?
Unable to cast object of type 'System.String' to type 'System.Web.UI.WebControls.Parameter'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Web.UI.WebControls.Parameter'.Source Error:

Here is my code behind... What am I doing wrong with grabbing the ClientID from the first stored procedure insert?

I have an application which runs successfully on a couple of my customer's machines but fails on a third. It seems to fail when opening the database:
Unable to cast COM object of type 'ADODB.CommandClass' to interface type 'ADODB._Command'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B08400BD-F9D1-4D02-B856-71D5DBA123E9}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=false; Initial Catalog=lensdb;Data Source = SQL
Before I got this error I was getting another problem (sorry didn't make a copy of that error's text) that made me think that adodb.dll simply wasn't loaded/registered. I got rid of that error by copying my adodb.dll onto the third machine and running gacutil /i. There is now an entry in winntassemblies for adodb.
Just in case you think it could be an obvious registry problem: when I started getting the current error I thought that maybe the registry needed updating and I merged the following lines into onto the target machine (from my dev machine):
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOTInterface{B08400BD-F9D1-4D02-B856-71D5DBA123E9}]

but, no change alas.
All three machines are running Windows 2000.
Any advice would be appreciated.

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

Hi,
I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:
this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);
this.mycourtsDataSet1.AcceptChanges();
this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);
This did not happen with VS2005/CE3.01.
I have tried changing all references to decimal (or money in CE3.5) without luck.
I'm beginning to think that string may be the way to go!!!!!!!
Can someone shed some light on my problem.
Thanks,
Later:
It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.
